The Systec ZHCR (Zero Hysteresis / Constant Run) Preparative vacuum pump is designed for membrane degassing of the HPLC mobile phase. Employing a patented closedloop, micro-stepping, RPM control-strategy permits the pump to run with continuously variable speed, providing quick pull-down at high RPM, and then sustaining a consistent vacuum level at low RPM.
